Gong Xinxian was originally a deity in heaven. She was in charge of the Ice Foil Sword, but due to an accident, the Ice Foil Sword fell into the human world. Therefore, the Emperor of Heaven punished her to go down to earth and endure calamity. He also erased all her memories in Heaven and asked her to go down to earth to retrieve the Ice Foil Sword.
Gong Xinye and Ling Wuye gave birth to a boy and a girl. The boy was named Ling Wuyuan and the girl was named Gong Xinxian. Since both sects have inherited the title of mountain master, they have different surnames.
Because Gong Xinye was framed, a sword pierced the elixir, and transformed into a ray of soul that was imprinted on the elixir.
Twenty years later...
Gong Xinxian fell into the water accidentally and was in a coma for three days...
The 21st century girl Lin Xinxian accidentally traveled into the body of Gong Xinxian. By chance, she went down the mountain to investigate what happened to her mother.
Intention: time travel
